News Corp. Digital Chief Jon Miller to Exit

Oversaw Effort to Turn Around MySpace

Jon Miller, News Corp.'s chief digital officer, is leaving the media giant at the end of September as the company prepares to split into separate entertainment and publishing businesses. He will serve as an advisor to the company through 2013, News Corp. said in a statement.

Since his hiring in 2009, Mr. Miller has set out to create a unified digital strategy for the company across businesses. He oversaw a turnaround attempt at MySpace, which the company bought for $580 million in 2005, but also its eventual sale to the ad network Specific Media, which paid $35 million for it. Mr. Miller has also been News Corp.'s representative on Hulu's board.

Earlier this year News Corp. contributed to $45 million in new funding for Roku, which streams digital video to TVs, in a deal that made Mr. Miller a Roku director.

Mr. Miller previously ran an investment firm with Ross Levinsohn, the former Yahoo exec, fueling speculation that the two may look to work together again. Asked about that prospect, Mr. Levinsohn said in an email that nothing was pending on that front. "Not as of now," he wrote. "He's a great friend and I know he will do great at whatever is next."

Mr. Miller has also served as CEO of AOL.

"While my time spent has been productive, it feels like the right time to exit," Mr. Miller said in the company's press release. "I look forward to pursuing new ventures that will lead me back into an operational role."
